This report analyzes the effectiveness of Iowa's "work support" policies – benefits such as earned income tax credits, public health insurance, child care assistance, and food stamps. When families receive the benefits for which they are eligible, Iowa's work supports can help families close the gap between low earnings and basic expenses. Rewarding progress in the workforce, however, remains a challenge. Small increases in family income can trigger sharp reductions in benefits, leaving families no better off – or even worse off – than before.
